Twl is correct, the Lamhorns would be an excellent choice and can be had new for less than $6K with a choice of drivers. I have DX3 in mine. I would have gone with AER but they are 16 ohm only and my amp is 8. I think they come in 8 ohm now but I'm not sure. You will need a good sub to go full range, but most convential multi driver speakers need one too.
You won't get more than a few watts from a 45 amp so speaker choice is critical. I must respectfully disagree with the notion that SET systems limit your choices in music. I can only guess that these folks have never heard a fully realized system. If you can get back issues of Listener magazine there are many reviews of SET amps and compatible speakers.
